Catching hook

ABSTRACT

The invention relates to a catching hook having a straight portion (1) which in one end is provided with a hook (2) and another straight portion (3) which in the end opposite to the hook is provided with a handle (4). The portions are displaceable relative to one another between a catching position when they are extended at a maximum to a transportation position when they are pushed together. The hook (2) is rotatably connected to the end of the first straight portion (1), a locking device (6) being arranged in that end to prevent the rotation of the hook when used in its catching position, and after release permit rotation to a weighing position. The handle (4) is rotatably connected to a supporting device in the form of a sleeve (7) which is slidingly arranged on the corresponding straight portion, the handle being pivotably connected to the sleeve and after release from the end of the straight portion rotatable to a weighing position. A counterweight (12) is attachable to the end of the handle portion so that the catching hook can be used as a balance scale.

The present invention relates to a catching hook, comprising twostraight portions which are arranged for displaceable movement relativeto one another between a catching position when the portions are inextended relationship to a transport position when the straight portionsare pushed together, one of said straight portions being in one endprovided with a hook and the other straight portion being provided witha handle at the end opposite to the hook.

A catching hook of the kind mentioned above is a fishing tackle which isused as an assisting device to lift heavy catching out of the water,thereby preventing the tackle from being damaged and the fish fromdisappearing. Usually the two straight portions are telescopicallydisplaceable relative to each other but this is of course noprerequisite for the invention.

The object of the present invention is to realize a catching hook whichthrough an easy measure can be used as a balance scale.

This object is realized according to the invention substantially by thefact that the hook is rotatably connected with the end of the firststraight portion and that locking means are arranged to preventrotational movement of the hook when used in catching position, andafter release of said locking means permit its rotation to a weighingposition, and that the handle is rotatably connected to a supportingdevice which is slidingly displaceable on the corresponding straightportion, said handle being pivotably connected to said supporting deviceand after release from the end of the corresponding straight portionbeing swingable to a weighing position, and that a counterweight isattachable to the end of the handle portion, whereby the catching hookcan be used as balance scale which is carried by means of the outwardlyswung handle.

An embodiment of the invention will now be described more in detail withreference to the accompanying drawings in which

FIG. 1 is a catching hook according to the invention in a catchingposition,

FIG. 2 is the catching hook now used as balance scale for lighterweights, and

FIG. 3 is the catching hook used as scale for heavier weights.

As appears from FIG. 1 a catching hook according to the inventioncomprises one straight portion 1 which in one end is provided with ahook 2 and another straight portion 3 which at its end opposite to thehook is provided with a handle 4. The two straight portions 1 and 3comprise in the embodiment disclosed two telescoping tubes which aredisplaceable between a catching position when the tubes are extended ata maximum as shown in the Figure, to a transport position when the tubesare pushed together as appears from FIG. 3. The hook 2 is rotatablyconnected with the end of the first tube by means of a through shaft 5and the hook can be blocked in catching position by means of a pin 6which prevents rotation of the hook and which after release permitsrotation to a weighing position as appears from FIGS. 2 and 3. Thehandle 4 is in a similar way rotatably connected to a supporting devicein the form of a sleeve 7 which is slidingly displaceable on thecorresponding tube portion 3. The upper side of the handle is reinforcedby means of a ledge 8 which in one end is attached to a shaft 9 in thesleeve 7. At the end of the handle there is an engagement member in theform of a locking screw 10 which by means of threads or a bajonet clutchfits in a corresponding recess 11 in the end of the handle portion. Inthis embodiment the handle 4 is made in the form of tube and has aninner diameter which fits the outer diameter of the handle portion 3whereby the handle can be telescopically displaced over the handleportion and can be attached to it by means of the locking screw 10.

As appears from FIG. 2 the catching hook according to the invention caneasily be transformed into a balance scale by releasing the pin 6 in theend of the hook portion whereby the hook can be pivoted around the shaft5 to a weighing position. The handle is released in the way describedabove by releasing the locking screw 10 from the recess 11 and thehandle can then easily be pulled out from the handle portion 3 and swungout to the weighing position shown on the Figure. Then a counterweight12 is attached to the end of the handle portion preferably in the samerecess 11 as the screw 10. In the position shown on the Figure when thetwo tubeformed portions are pulled out of one another at a maximum thebalance scale is ready for weighing of relatively light catching and thefirst scale graduation 13 on the handle portion 3 is consequentlyadapted for weighing in this position.

The catching hook according to the invention also permits weighing ofheavier catching whereby the two tubeformed portions 1 and 3 are pushedtogether to a position which is shown on FIG. 3. The tubeformed portion3 with the greater diameter is thus provided with a further scalegraduation 14 which is adapted for weighing in this specific position.

Weighing of catching is carried out in a conventional way by displacingthe sleeve 7 to a position where balance occurs whereby the position ofthe sleeve on the tubeformed portion 3 is read out.

I claim:
 1. Catching hook comprising two straight portions which arearranged for displaceable movement relative to one another between acatching position when the portions are in extended relationship, to atransport position when the straight portions are pushed together, oneof said straight portions being in one end provided with a hook and theother straight portion being provided with a handle at the end oppositeto the hook, characterized in that the hook is rotatably connected withthe end of the first straight portion, and that locking means arearranged to prevent rotational movement of the hook when used incatching position, and after release of said locking means permit itsrotation to a weighing position, and that the handle is rotatablyconnected to a supporting device which is slidingly displaceable on acorresponding one of said straight portions, said handle being pivotablyconnected to said supporting device and after release from the end ofthe corresponding straight portion, being swingable to a weighingposition, and that a counterweight is attachable to the end of thehandle portion, whereby the catching hook can be used as balance scalewhich is carried by means of the outwardly swung handle.
 2. A hookaccording to claim 1, characterized in that the hook is rotatablyconnected to a corresponding one of said straight portions by means of athrough shaft and is non-rotatably secured to said portion by means of athrough pin.
 3. A hook according to claim 1, characterized in that thesupporting device comprises a sleeve which is slidingly arranged on thehandle portion, the peripheral portion of said sleeve being providedwith a pivot axle for the rotational movement of said handle.
 4. A hookaccording to claim 3, characterized in that the handle is telescopinglydisplaceable over the end portion of a corresponding one of saidstraight portions and is attachable to the end of the latter by means ofan engagement member cooperating with a recess in the end surface.
 5. Ahook according to claim 4, characterized in that the counterweight isattachable in the recess in the end surface of the handle portion.
 6. Ahook according to any of the preceding claims, characterized in that thehandle portion is provided with two graduated scales, one of which isintended for weighing when the two portions are extended to catchingposition, whereas the second is intended for weighing when the twoportions are pushed together to transport position.
